FLASHING-BLOCK.

To all whom it may concern:

Be 'it known that I, ISIDOR PoMnRANTz, a

I citizen of the United States, residing at 608.

'panying drawings,-and to the letters and figures of reference markedthereon, which form a part of this specification.

My inventionrelates to flashing blocks, and more particularly to adevice of that character adapted for use in the wall of a buildingadjacent a roof, in order that roof flashing may be applied and anchoredthere-- to; the principal object of the invention being to provide ablock to which the flashing may be secured and permanently anchored,irrespective of expansion and contraction of the flashingyand havingmeans for carrying an auxiliary flashing, whereby water is deflectedaway from the point of anchorage of the main flashing. In accomplishingthis object I have provided improved details of structure, the preferredforms of which are illustrated in the accompanying drawings, whereinFigure 1 is a sectional perspective of a building wall comprising ablock vconstructed according to my invention, and showing the main roofand hood flashing, 1n combination with the block. Fig. 2 is anenlarged-sectional perspective of the flashing block, here shown to bein the nature of an ordinary hollow tile, and more partlcularly'illustrating the nailing block for the roof flashing. Fig. 3 is anenlarged deta1l perspective of the flashing block, showing the nailingstrip partially removed.- Fig. 4.

is a sectional perspective of a modified form of block. Fig. 5 is amodified form or nailing strip. Fig. 6 is a detail perspective of afurther modification of the flashing block.

Referring more, in detail to the parts :--1 designates the wall'of abuilding, and 3 the roof, which parts may be of any ordinaryconstruction, except that the wall 1 comprises aflashing block 5 of tileor the like which faces inwardly a short dlstance above the roof. Eachof the blocks 5 comprises a Specification of Letters Patent.

lower groove 9, preferably dove-tail in constructlon, and adapted forcontaining a nailing strip 6; the outer face of which is flush with theouter face of the block, and an upper groove 8 which is also preferablydove-tail in shape and extends parallel with the lower groove 9throughout the length of the block.

The roof flashing 4, which may be of any ordinary type, is extendedupwardly along the wall at the edge of the roof and nailed or otherwisesecured to thenailing strip '6, so that its upper edge terminates belowthe upper block groove 8. Projected into the upper groove 8 is a hoodflashing 7 the lower edge of which overhangs the upper edge of the roofflashing 4, while its upper edge is held in the groove 8 by cement,orthe like, which is filled intothe groove after the flashing has beenplaced.

In Fig. 4 I have shown a modification of the above structure, whereinthe nailing strip 15 is set into the, wall 14 and provided with upperandlower recesses 1819, into which plaster or cement that anchors the stripin place is projected inorder to form keys for holding the strip inplace With .this construction, the roof flashing 20,is

nailed to the outer face of the strip and the hood flashing 16 issecured to; the upper] edge of the strip, so that it is'secured, in theplaster within the wall andjoverhangs the'upperedge of the roofflashing.

' In the modification shown in Fig. 5, 22 designates theblock which isseated in the wall and has upper and lower recesses 25-26 for receivingthe cement or plaster as described with reference to Fig. 4. block 22has a dove-tail groove 27 in its outer face within which a nailing strip23 is removablyv mounted. With this construction the hood flashing isset into the wall at the upper edge of the block so that it overhangsthe nailing strip 23, and the roof flashing (not shown) is secured tothe nailing strip after the block has been set and before the hoodflashing is bent down to In the modification shown in Fig. 6, the

block 30 isprovided with a longitudinal groove in .its upper face, intowhich the hood flashing may. be projected in order to securely anchorthe same in place; the block having a "longitudinal dove-tail 32, likeThe those heretofore described, and adapted for containing a nailingstrip 33 of the character described.

In using my invention, the flashing blocks of tile or the like are setinto the Wall of a building, While the latter is being erected, andslightly above the roof position.

When the roof is in place, the roof flashing is applied thereto and theedges of the flashing turned upwardly along the Wall and nailed to thenailing strip. After the roof flashing has been secured to the nailingstrip of the block, the upper edge of the hood flashing is projectedinto the anchoring groove and a key of cement filled into the groove tohold the roof flashing thereto; the hood flashing being of suflicientWidth to overhang the upper edge of the roof flashing, so that rain ormelting snow passing down the side of the Wall will be deflectedover-the upper edge of the roof flashing instead of passing back of theflashing to rot the flashing and leak into the building.

Having thus described my invention, What I claim as new therein, anddesire to secure by Letters-Patent, is:

A roggle block formed in a single piece with parallel upper and lowergrooves in one side face thereof, a main flashing bearing flat upon saidface, means for securing the main flashing to the lower grooved portionof the block, a counter flashing bearing upon the main flashing, andmeans for anchoring the upper edge portion of the counter flashingwithin the upper groove.

In testimony whereof I aflix my signature in presence of two Witnesses.

ISIDOR POMERANTZ.
